In a triangle `(1)/(a+c)+ (1)/(b+c)=(3)/(a+b+c) ,` then the value of the angle C is-

In a triangle ABC, if (1+(a)/(b)+(c)/(b))(1+(b)/(c)-(a)/(c))=3, then the angle A is

In a triangle ABC, if (1+(a)/(b)+(c)/(b))(1+(b)/(c)-(a)/(c))=3 then the angle A is equal to

In any triangle ABC, if 1/(a+c) + 1/(b+c) = 3/(a+b+c) then show that, C=60^(@) .

In a triangle A B C\ a : b : c=sqrt(3)\ :1\ :\ 1, then the triangle is- right angled triangle (b) abtuse angled triangle acute angled triangle, which is not isosceles Equilateral triangle

let A, B, C are angles of a triangle and tan ""A/2=1/3,tan ""B/2=2/3, then the value of tan ""C/2 is-

If A, B and C are angles of a triangle such than tan A = 1, tan B = 2, then what is the value of tan C ?

In a triangle ABC, angle A = 60^(@) and b : c = (sqrt3 + 1) : 2 , then find the value of (angle B - angle C)

In a triangle ABC, angle A = 60^(@) and b : c = (sqrt3 + 1) : 2 , then find the value of (angle B - angle C)
